Description
Cosmetic composition comprising at least one volatile linear alkane with a fatty ester or alcohol and at least one plant oil
The present invention relates to a cosmetic composition compri sing one or more volatile linear alkane(s), one or more fatty alcohol(s) or ester(s) and one or more pl ant oil (s), to its use for the cosmetic treatment of keratin material s, preferably keratin fibres such as the hair, and to a cosmetic process for treating keratin material s using the said composition.
In the field of hair treatment, the use of volatile solvents i s known in rinse-out or leave-in haircare products.
These volatile solvents, which are generally liquid fatty esters, hydrocarbon-based oil s of i sododecane or i sohexadecane type, and/or silicone oil s, may especially give ri se to problem s in terms of a greasy feel, lack of sheen, and stiff, hard hair.
There i s thus still a need to obtain compositions that can avoi d the drawbacks mentioned above.
The Applicant has now di scovered, surpri singly and unexpectedly, that the combination of one or more volatile linear alkanes, one or more fatty alcohol(s) or ester(s) and one or more pl ant oil s makes it possible to avoid the drawbacks mentioned above.
In particular, the composition according to the invention can afford hair that i s smoother, uniform and/or more supple, at the time of rinsing. On wet hair, hair that i s easier to di sentangle or more tonic and/or whose roots are more lifted (at the roots, the hairs are not flattened onto the scalp, but form an angle, which gives volume) i s obtained. Hair treated with the compositi on according to the invention dries rapidly . In addition, the dry hair is more supple and/or has a smoother feel and i s shinier.
Thus, one subj ect of the invention is a cosmetic composition compri sing, in a cosmetically acceptable medium :
- one or more volatile linear alkanes,
- one or more plant oil s,
- one or more C8 to C50 fatty ester(s) or alcohol(s),
the esters being different from the plant oil s.
A subj ect of the invention is al so the use of a composition according to the invention for the cosmetic treatment of keratin material s, preferably keratin fibres such as the hair, especially as a rinse-out haircare product.
Another subj ect of the invention i s a cosmetic process for treating keratin material s, preferably keratin fibres such as the hair, using the said composition.
The term "one or more volatile linear alkane(s)" means, without preference, "one or more volatile linear alkane oil(s)" .
Volatile linear alkanes
A volatile linear alkane that is suitable for use in the invention i s liquid at room temperature (about 25 ° C) and at atmospheric pressure ( 101 325 Pa or 760 mmHg) .
The term "volatile linear alkane that i s suitable for use in the invention" means a linear alkane that can evaporate on contact with the skin in less than one hour, at room temperature (25 °C) and atmospheric pressure ( 101 325 Pa), which i s liquid at room temperature, especi ally having an evaporation rate ranging from 0.0 1 to 1 5 mg/cm2/minute, at room temperature (25 ° C) and atmospheric pressure ( 101 325 Pa) .
Preferably, the volatile linear alkane(s) that are suitable for use in the invention have an evaporation rate ranging from 0.01 to 3 .5 mg/cm2/minute and better still from 0.01 to 1 .5 mg/cm2/minute, at room temperature (25 °C) and atmospheric pressure ( 10 1 325 Pa) .
More preferably, the volatile linear alkane(s) that are suitable for use in the invention have an evaporation rate ranging from 0.01 to 0.8 mg/cm2/minute, preferentially from 0.01 to 0.3 mg/cm2/minute and even more preferentially from 0.01 to 0. 12 mg/cm2/minute, at room temperature (25 °C) and atmospheric pressure ( 10 1 325 Pa) .
The evaporation rate of a volatile alkane in accordance with the invention (and more generally of a volatile solvent) may especially be evaluated by means of the protocol described in WO 06/01 3 413 , and more particularly by means of the protocol describ ed below.
1 5 g of volatile hydrocarbon-based solvent are placed in a crystallizing di sh (di ameter: 7 cm) placed on a balance that i s in a chamber of ab out 0.3 m3 with regulated temperature (25 °C) and hygrometry (50% relative humidity).
The volatile hydrocarbon-based solvent i s allowed to evaporate freely, without stirring it, while providing ventilation by means of a fan (Papst-Motoren, reference 8550 N, rotating at 2700 rpm) pl aced in a vertical position above the crystallizing di sh containing the volatile hydrocarbon-based solvent, the blades being directed towards the crystallizing di sh, 20 cm away from the bottom of the di sh.
The mass of volatile hydrocarbon-based solvent remaining in the crystallizing di sh i s measured at regular time interval s.
The evaporation profile of the solvent i s then obtained by plotting the curve of the amount of product evaporated (in mg/cm2) as a function of time (in minutes) .
The evaporation rate i s then calculated, which corresponds to the tangent to the origin of the curve obtained. The evaporation rates are expressed in mg of volatile solvent evaporated per unit area (cm2) and per unit of time (minutes).
